About the project

Launched in October 2018 and for a duration of 3 years, ASTERIQS aims at developing precise sensors made from diamonds including an atom-like defects like NV centres to measure quantities such as magnetic field, electric field, temperature or pressure and at investigating the structure of single molecules or spintronics devices.

Florian Schreck
Coordinator of iqClock
Progress on iqClock | Use Case in Sensing / Session 1 / Tuesday, Nov 3 & Thursday, Nov 5
Prof. Florian Schreck (University of Amsterdam) works on quantum sensors, simulators and computers based on ultracold strontium gases. These devices exploit quantum properties to perform tasks that are out of reach for classical devices. He is coordinator of the Quantum Flagship project iqClock, which aims to bring the best clocks in the world closer to the market. Within this project his research group is developing a new generation of optical clocks, superradiant clocks. Related to this project his group recently created the first Bose-Einstein condensate of ultracold atoms in steady-state, a great starting point for future continuous atom lasers that are useful for quantum sensing. His group has also built a quantum simulator based on single Sr atoms loaded into an array of optical tweezers. These atoms can be used as qubits, and will be the basis of quantum simulations, optimizations and computations. Finally his group is exploring ultracold Rb-Sr mixtures with the goal of creating an ultracold gas of RbSr molecules, suitable for the quantum simulation of systems with dipolar interactions.

About the project

The iqClock project aims to boost the development of optical clocks using quantum technology to be ultra precise and affordable. These clocks will improve technological developments and scientific applications that are beneficial to the society.


The main objective of the iqClock project is to kick-start a competitive European industry for optical clocks as well as to strengthen and accelerate the pipeline of clock development. These clocks, making use of quantum technology, will be ultra-precise and have many applications in science, technology and society. For most applications, transportable, simple-to-use and affordable, optical clocks are needed and we expect our project to make a significant step towards providing them.

About the project

Cardiovascular diseases are one of the most common causes of death worldwide. Therefore, it is necessary to develop personalized medical solutions to improve the chances of curing patients. In order to do so, the metabolic process of heart tissue needs to be understood and observed on a molecular level. Current methods do not allow this in high resolution, and they furthermore rely on radioactive substances.

The MetaboliQs project is working to leverage room-temperature diamond quantum dynamics to enable safe multimodal cardiac imaging which can help better diagnosis of Cardiovascular Diseases

Frank’s main areas of expertise are superconducting quantum circuits, ultrastrong light-matter coupling, and propagating quantum microwaves for communication and sensing.

About the project

QMiCS sets up a quantum microwave local area network cable over a distance of several meters. We will use this architecture to implement quantum communication protocols such as teleportation between two superconducting quantum nodes.

Since our approach does not require any of the notoriously loss‑prone frequency conversion techniques, our platform will be highly beneficial for distributed quantum computing.

In addition, we take first steps towards the ambitious goal of radar-style quantum sensing with microwaves. Major milestones here are the implementation of microwave single photon detectors and the development of a roadmap towards commercial applications in later phases of the Flagship.

Progress on PASQuanS / Tuesday, Nov 3

About the project

PASQuanS (Programmable Atomic Large-Scale Quantum Simulation) aims to advance quantum simulator technologies. It builds on the achievements of the most advanced quantum simulation platforms to date, based on atoms and ions.

New ideas and applications are expected to emerge from a close dialogue as it will be realized within PASQUANS.

About the project

Scalable Two-Dimensional Quantum Integrated Photonics, S2QUIP, aims to develop scalable cost-effective on-chip quantum photonic hybrid microsystems by integrating two-dimensional semiconductor materials (2DSMs) in state-of-the-art CMOS compatible nanophotonic circuits. S2QUIP will take advantage of the recent emergence of 2DSMs to achieve an efficient and coherent spin-photon interface incorporated into complex on-chip quantum photonic circuits resulting in portable, low-power consumption and market-scalable quantum photonics technologies. The use of 2DSMs provides extraordinary advantages over traditional semiconductor materials previously employed, due to their atomically-flat nature and intrinsic physical properties. Single photon generation in visible wavelengths has recently been demonstrated with 2DSMs, paving the way for S2QUIP to generate entangled photon states at record rates that will unlock new quantum technologies.

The S2QUIP project has received founding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 820423.

Natalia Korolkova received her PhD in theoretical quantum optics in 1996 from Moscow State University. In 1996/1997 she was appointed as a postdoctoral researcher at the Department of Optics, Palacky University in Olomouc, Czech Republic, in the field of quantum statistics of light fields, non-classical light and quantum cryptography.In 1997 she joined the Quantum Metrology group at Erlangen University, Germany, as a Humboldt Fellow with topics quantum multimode correlations of bright optical beams and quantum optics with fiber solitons. During 1999-2003 she was leading the Quantum Information group at the Center of Modern Optics at the University of Erlangen, Germany. Since September 2003 Natalia Korolkova is with the School of Physics and Astronomy at the University of St. Andrews, Scotland. Her expertise lies in quantum information processing using quantum continuous variables of light and matter, where she has published pioneering works and well received reviews.

About the project

The goal of the project is to deliver deterministic and compact sources of highly non-classical states, from sub-Poissonian light to multi-mode entanglement, all using a single technological platform.

The consortium PhoG will build working prototypes and develop the technological foundation for the applications of these sources in advanced optical imaging and metrology.

The proposed sources will be based on a novel paradigm in photonic devices: coherent diffusive photonics operating with dissipatively coupled optical waveguides. The project will demonstrate that light can flow diffusively while retaining coherence and even entanglement, can be effectively equalized and distributed in a controlled way by means of dissipative coupling. Such unique light propagation regimes will be realized with the help of a photonic analogue of a tight-binding lattice using coupled waveguide networks in linear and non-linear glass materials. The decisive role is played by the linear and nonlinear engineered loss. These coherent photonic devices will be fabricated by ultrafast laser inscription. The dissipative coupling will be realised by coupling each pair of the waveguides carrying optical signal to a linear chain of waveguides that act as a dissipative reservoir. Efficient quantum diagnostic methods will be developed to verify the source characteristics and to assess their technological readiness. We expect coherent diffusive photonic devices to find applications in photonic networks and in a range of metrology tasks, potentially also for simulations of complex quantum dynamics. The specific project goals are:

(1)   to implement a family of compact sub-Poissonian photon guns, capable of robust generation of mesoscopic non-classical and entangled states at 1550 nm and at 852/894 nm;

(2)   to perform a feasibility study of their applications in entanglement-enhanced imaging and atomic clocks aiming at the 2-4 times better clock frequency stability.
